Take a look at the second link above. That page has a variety of pots but I would stick with those that have a 1/4" shaft diameter with a long shaft If you are using it for operator control you will want some method of supporting the shaft so that a overzealous operator doesn't bend it into a modern object d' art. Stay away from mutliturn pots or those with screw driver shafts. You need 100K for the OI interface wired as shown in the OI manual. The OI monitors the it's inputs and if it believes a joystick has become unplugged it sends a PWM 127 to the appropriate RC channel. Similar pots are available from Mouser and some are available at Radio Shack. Be advised that not all stores keep the same stock in the store.
